I’m just appreciating this kind teacher is still reading RUclips comments to this day 😭
Thank so much for making these videos. These are definitely helping me to prepare for testing out of geometry honors.
You are so helpful. i appreciate the explanation it was making everything easy. Thanks
Thank you, Joann! Your videos will help my child this year and me as a refresher so I can assist.
I just found your channel, I love how detailed and nice are you explanations, thanks a lot.

Being taught terms like postulate and axiom are so helpful in being able to- I'm not sure how to phrase it- concretize, solidify, structure my understanding of large subjects such as geometry. These sorts of fundamental terms are so often glossed over, or if they are mentioned, their meaning is never explored. Definitions are so important when trying to learn a subject, as they indicate why the relationships exist; rather than how I've always been taught: "just understand what the relationships are." My brain doesn't or won't work that way.
Anyway, thank you!
I've been wanting to teach myself geometry for a while since I've already learned everything in alg 1 but still have to take the class and this is really helpful :)
Your videos help me during school and I went from B’s to all A’s thank you so much..
That makes me feel like my work is worthwhile! Thank you for letting me know. I'm proud of you for being proactive about your future and bettering yourself.
Thank you so much! This will be great for my homeschooled high schooler!!!
These videos are so clearly presented. I'm helping my grandson with honors geometry, and they are helping both of us!
Lots of lots of love from Malaysia!
It's the middle of the year and I haven't learned anything, this is really helping thank you so much
You are so welcome!
All of your videos are amazing. They really helped me. My teacher once put you on. Then for the summer I have been watching you since grade 1 now I am almost in grade 5. Thank you for putting time and effort in your videos it really helps a lot of people.
If you keep watching my playlists, you may skip grades like my granddaughter!
She skipped 3rd Grade and now is beginning 5th Grade in the Fall. But, she understands a lot of Algebra! Math is easy when you preview it before the teacher teaches it.
Keep going! xxxooo
This is gonna save me next year
Remember, by hitting the like button on any of my videos that help you, you tell RUclips to put my videos higher on their algorithm and search list! It also lets me know if you understood my lesson, for me to know if I explained it well enough. 😊
I'm watching your videos to get informed for Geometry this year,at least I will have some knowledge before starting the class pretty soon :).
I'm proud of you for doing this! :-)
so great. I've been struggling with geometry, as i am more of an algebra girl
You may surprise yourself! When I was in 8th grade I very easily and quickly rushed through Algebra 1. I was nervous to do geometry. I ended up getting an A in Geometry though. There was just something about the spatial relationships that made sense to me. I will always love algebra though. Let me know if you need any more help. You can ask me questions in the comments, or you can go to my Facebook page and ask me questions there.
@@JoAnnsSchool ok, thank you so much!
Omg, you are a great teacher, thanks a lot.
I love Geometry!
Me too! :-)
Very informative ..thank you so much ... From India.
I love this teacher, she literally predicted what i was gonna do at the end, I was gonna write down the vocabulary words in this lesson. 8:55 (just got into highschool btw, trying to learn ahead of time, and these videos are really helpful!!)
ME TOO. I just got into highschool, and I don’t want to go through the struggle of learning geometry in September so I’m doing it now since I have more free time!
Amazing 😉
Great video
my son is using this for his online school thx
Thanks u helped me alot keep going ur the best 👌
beautiful notes!!!!
THANK YOU SO MUCH MAAM💛
I’ve been struggling for weeks of my teacher not knowing how to do their job. This solved it in minutes
I'm so glad you found it helpful! This is the first lesson of an entire high school geometry course. All the lessons are in a playlist, in consecutive order. High School Geometry Course Playlist

JoAnn's School That’s how I found it! Thank you so much for uploading this. My teacher will just tell me to look at my book when I tell him that I don’t get it 🙄. The worst part is that supposedly it is my fault 🤷♂️.
@@davidortiz3015 , wonderful that you saw it. Let your friends/classmates know about it also. :-)
JoAnn's School I definitely will 👍
Great instructor
I love geometry ❤️, thanks
Thank you for this lesson, but is there a website of some sort where we, the students, can execute what we learned or get some math problems about the lesson. It'd be really helpful
It follows the Holt McDougal textbook. This site may help you, but you'll need to create a login. study.com/academy/course/holt-geometry-help.html
And this seller ha a used one available for $5.99 www.alibris.com/search/books/isbn/9780547647098Google&?NMPi_Smart_Shopping&NMPi_Smart_Shopping&ds_rl=1264488&ds_rl=1264488&gclid=EAIaIQobChMIxfG9lsKq6wIVUr7ACh04QAX9EAQYASABEgLWcfD_BwE&gclsrc=aw.ds
These videos help me fall asleep when I can’t fall asleep
LOL. Okay.
Thank you im doing geomitry over summer so i can get to alg 2 by tenth grade
She has so many whiteboards
It's labeled by "its" endpoints, not "it's" endpoints.
3:52 Could you please explain the difference between opposite rays and lines? They look really similar and I don’t think I’ll be able to tell them apart.
Opposite rays point in opposite directions. They are two rays that both start from a common point and go off in exactly opposite directions, forming a single straight line through the common endpoint.
@@JoAnnsSchool Ohhhh thanks!
Why is A and D non Coplanar ? Doesn't A fall into that Plane?
If you are referring to 1:45, D is a bit above the plane that A, B, and C are on. A and D are non-coplanar to each other. Coplanar means "lie on the same plane". :-)
Hello, so all I wanted to say is that I skipped basic 8th-grade pre-algebra and went straight to Algebra 1. As a result, I have little to no knowledge of what systems I am supposed to use in geometry. Do you think I should learn the basics or just start the lessons and just learn as I go? Thanks!
It depends. Did you barely pass Alg 1? Did you get an A in Alg 1? Everything that is taught in 8th grade is re-taught in Alg 1, but with more depth. Math lessons are ''layered''. A concept in introduced in one year, then the next year it's covered again but with more detail. Like addition is taught in Kindergarten such as 1+2, then in 1st grade they teach 10+12.
I really try to re-teach and review in Geometry though.
Maybe you just need a quick refresh, then move forward? Try this playlist :-)

Hey it’s me again 😁 in the video at 1:37 it shows about being a collinear or a non Collinear I 100% understand how D is an non-collinear but how is A and B a non-collinear what difference between them and why they are and C isn’t as well this goes with the non-coplanar ...how is A a non-coplanar?
The answer is at 1:20. Points that lie on the same line are collinear. D is not on the line, so it's NON-collinear. We can break down the word, co meaning "together" and linear meaning "line" :-)
JoAnn's School yeah but you also said A,B are also non-collinear how come ? Sorry if my question confusing I’m not sure how to explain it.
@@angiguzman3786 , It's the relationship between the three points. A, B & C have a collinear relationship. A, B and D do not have a collinear relationship so they are non-collinear. :-)
Do you have a workbook with answers that you recommend that works together with the lecture book you recommended?
A ''Teacher's manual'' can be purchased for each grade level of my playlists. For this geometry playlist, I found an online site pdfgoal.com/downloads/geometry_teacher_edition_holt_mcdougal_2012
I googled "teacher's manual Holt McDougal Geometry, copyright 2012"
@@JoAnnsSchool 2012 Copyright as you say you searched for these pdf file, but for the books it has a 2011 copyright year zeroth edition. Will a 2011 work fine with your videos? I have to create a profile for that link you sent. And I will later
@@JoAnnsSchool also it seems each book is published my state. Does that mean they are al different?
Textbook companies publish different state versions because some states have strict rules or lenient rules for what the state will allow the students to be taught. A Mississippi book may be slightly different than a California book. There are also regular books that are used by many states, like a general textbook. Either book will be fine. Their differences are usually slight. :-)
That's normal. Yes, 2011 will work fine. :-)
:)
Im taking Geometry honors starting about two weeks from now, I know absolutely none if this
@@aidankiehl2932 This is the first lesson. Take notes. Watch my videos in their consecutive order as they are in the playlist, BEFORE the school lessons and you'll be ahead! If you did okay in Algebra 1, you should be able to follow along easily. My comments are open and I still answer them. 🥰
Could you tell me what textbook are you using?
